Abstract: PURPOSE:To prevent the loosening of a coil due to the spring back of a wire by applying tension to the wire while being wound, releasing the tension to the wire immediately after wound tightly and holding the side of the coil until immediately before the next wire is wound around the winding region of a core. CONSTITUTION:Rollers 31'-34' are opened, a wire 3 is separated from a track 4 and a solenoid 45 is attracted for driving immediately before the wire is wound around the winding region 22 of a core 20 by passing the gap between a track base 1 and a track cover 2. Links 48, 48' are turned by the force of an extension spring 44 for returning, a pawl 49 recedes and descends and the next wire is wound around the winding region 22 of the core 20. Immediately after winding tightly by applying tension, the attraction of the solenoid 45 is released again and the side of a coil 30 is held by a pawl 39. This prevents the loosening of the coil due to the spring back of the wire 3.

Title: Transmitting antenna for medium frequency wave radio broadcasting
Inventor: KATOU YASUTAROU
IPC: H01Q9/34
Filed: 1981-05-18
Abstract: PURPOSE:To prevent the titled antenna from danger due to the falling of thunderbolts without connecting an insulator to a guy by hanging plural guys from the top of  a base-grounded steel tower having the height of 3/4 wavelength from the ground and  exciting the one of these guys so that the top of the tower is made voltage antinode. CONSTITUTION:A steel tower T has the height of 3/4 wavelength. If standing wave is  generated in the steel tower T, the base part C of the tower is made voltage node because it is earthed and the top A of the tower is made voltage antinode. A reactance  X is connected to the lower end of a guy G2 hung down from the top A so that the standing wave generated in the guy G2 is uniformed with the standing wave of the  steel tower 7. Excitation of the antenna from a signal source S is achieved at the  lower end of a conductor D0 stretched between a guy G1 hung down from the top A  and the steel tower T on the way of which an insulator I is connected. Consequently, a subrobe with a high wave angle is suppressed and irradiation in the horizontal direction is increased. Moreover, the connection of the insulator is unnecessary and the  steel tower is prevented from the danger due to the falling of thunderbolts because the  tower is earthed.
